Hi everyone, I just bought this 14-15 mm loose golden south sea pearl on Etsy (I know buying pearls online is risky, but I really want to try it out first.) I ask the owner to do a half drill for me. As you can see, there are some blemish, which I don't mind, but there is something like a "ridge" right at the drill hole (sorry I don't know how to describe it more accurately). I don't if that is normal. I also think this pearl looks a little bit different in luster than my the other golden south sea pearl (this one I pick it by myself at Gem show, should be real). Therefore, I was wondering if anybody can help me to check if this is a real golden south sea pearl. Any idea and advice will be appreciated. Thank you a lot.
